Screen Printing

Cricket

Cricket is a bat-and-ball sport competition by two teams, usually of eleven players each. A cricket match is played on a grass field, approximately oval in shape, in the centre of which is a flat strip of ground 22 yards (20.12 m) long, called a cricket pitch. A wicket, regularly made of wood, is placed at each end of the pitch.

The bowler, a player from the field team, bowls a hard, fist-sized cricket ball from the locality of one wicket towards the other. The ball usually bounces once before feat the batsman, a player from the conflicting team. In defence of the wicket, the batsman plays the ball with a made of wood cricket bat. Meanwhile, the other members of the bowler's team stand in a variety of positions around the field as fielders, players who retrieve the ball in an effort to stop the batsman scoring runs, and if possible to get him or her out. The batsman — if he or she does not get out — may run between the wickets, exchange ends with a second batsman (the "non-striker"), who has been waiting near the bowler's wicket. Each finished exchange of ends scores one run. Runs are also scored if the batsman hit the ball to the border line of the playing area. The match is won by the team that score more runs.
